UNITED SAS W. D. BALLARD, OF KANSAS CITY, MISSOURI.

STEAM-BOILER FURNACE.

Specification of Letters Patent No. 25,713, dated October 11, 1859.

To all whom it may concern.'

Be it known that W. D. BALLARD, of Kansas City, in the county of Jacksonand State of Missouri, have invented a new and useful inprovement inSteam-Boiler Furnaces; and I do hereby declare that the following' is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which-Figure 1 is a central vertical longitudinal section of a boiler andfurnace taken in the plane indicated by the line o@ :0 of Figs. 2 and 3.Fig. 2 is a transverse vertical sec.- tion of the same in the planeindicated by the line y fy of Figs. l and 3. Fig. 3 is a horizontalsection of the same in the plane indicated by the line a e of Figs. land 2.

Similar letters of reference indicate corresponding parts in the seve alfigures.

This invention consists in a novel arrangement of a ire place, settingand external 'tlues in combination with what is known as a two tineboiler whereby the several parts of the heating surface are exposed in avery effective manner to the action of the fire and inflamed and heatedgaseous products of combustion.

To enable others to make and use my invention I will proceed to describeits construction and operation.

A is the boiler supported at its ends, and at such other points in itslength, as may be desirable, on piers and completely inclosed by fourwalls a` a b Z), and a superincumbent arch or roof c, some distanceabove the top thereof. B, is the fire-place, and C, the ash pit,arranged under the middle of the length of the boiler, and having doorsin one of the side walls a a.

D is a mud pipe arranged below and transversely to the boiler over themiddle of the grate and connected with the bott-oni of the boiler by apipe d.

f, f are horizontal partitions of masonry extending the whole length ofthe boiler, between the sides of the boiler and the side walls a. a., ata level above the tops of the two flues e, e.

g is a partition extending from the mud pipe upward all around theboiler as high as the partitions f, f, dividing the space at the sidesof the boiler, b-elow the partitions j", f, into two equal parts. h.,7L, are two similar partitions, one at each end of the boiler extendingentirely across the spaces between the ends of the boiler' and the endwalls each of said partitions extending horizontally from one of thecorner piers below one of the flues c, e, to a point opposite the centerof the boiler from thence upward between the two tlues to a pointy abovethem and from thence horizontally to the opposite corner pier, but thetwo partitions being arri nged each in a manner the reverse of theother, that is to say, one passing below the flue, above which the otherpasses and vice versa.

F is the chimney situated directly over the middle of the boiler anddirectly over the fire.

G, Gr, are doors for cleaning the flues e, e.

The course of the draft is indicated by arrows in the several figures,viz., from the re, in opposite directions, along the bottom of theboiler and those parts of the sides thereof below the partitions, ,t f,and under the partitions, z. L., at the ends thereof. The heated gaseousproducts of combustion on their arrival at the ends of the boiler arecaused by the partitions, 7L. 7L, to pass in opposite directions throughthe boiler flues, e, e, and so to arrive at the opposite ends above thesaid partitions, It 7L, whence they escape over the top of the boiler tothe chimney.

that I claim as my invention and desire to secure by Letters Patent is YThe arrangement of the fire place B, the partitions f, f, g, 7L, 71, ofthe setting and the chimney F, substantially as herein described, withthe two flued boiler.

W. D. BALLARD.
